NEET 2021 Physics Dimensional Analysis MCQ Question
Type: MCQ-conceptual-Easy-Class 11
If E and G respectively denote energy and gravitational constant, then has the dimensions of :
A
[M²] [L⁻¹] [T⁰]
B
[M] [L⁻¹] [T⁻¹]
C
[M] [L⁰] [T⁰]
D
[M²] [L⁻²] [T⁻¹]
Correct Answer
Option A
Detailed Explanation
The dimensional formula for energy is [M L² T⁻²] and for gravitational constant is [M⁻¹ L³ T⁻²]. Dividing these gives [M² L⁻¹ T⁰].
